ACAM filter transmission curves
Individual transmission curves can be obtained from the
ING filter database.
For convenience, some of these curves (copied from the database in July 2011)
are compared below with the manufacturer's data:
1 - New Sloan u, g, r, i, z filters from Asahi Manufacturer's data:
ING transmission scans (z not scanned):
2 - Old Sloan r, i, g1, g2 filters ING transmission scans:
The FWHM bandpasses of the Bessell U, B, V, R and I filters are ~ 640, 1040, 890, 1360 and 3220 A respectively. The effective bandpass in Bessell I will be determined in part by the quantum efficiency of AUXCAM, which has dropped to ~ 0.1 by wavelength 10000 A. Manufacturer's data:
ING transmission scans (V is not usable, R has not been scanned):
